Product Details

The Optronics A75TC trailer adapter provides a reliable connection between your towing vehicle's 7-way blade (RV-style) connector and a trailer equipped with a 5-way flat connector. This essential adapter allows you to tow light-duty trailers with basic lighting functions using a vehicle wired for larger RV or heavy-duty trailer connections.

Key Features:

  • Converts 7-way blade (round) plug to 5-way flat connection
  • Compatible with standard trailer lighting circuits including running lights, brake lights, and turn signals
  • Compact, durable design for easy storage in glove compartment or toolbox
  • Weather-resistant construction for reliable performance in various conditions
  • Molded connectors ensure secure, corrosion-resistant connections

This adapter is ideal for occasional use when switching between different trailer types, eliminating the need to rewire your vehicle or trailer. The 7-way blade connector is commonly found on trucks and SUVs equipped for RV towing, while 5-way flat connectors are standard on utility trailers, boat trailers, and other light-duty applications.
